Question

Capacitor circuit

Answer 1

The switch shown has been in position A for long time. At time =0, the switch moves from A to B. Determine v(t) for t>0 across capacitor whose capacitance is 0.5mF.. And calculate its value at t=4

Answer 2

What im guessing is that only we will consider The right hand circuit, but i dont know im right, cause it says at time =0, it change position , hence capacitor dint get time to charge from left hand part of circuit

Answer 3

first of all what are the poles of the voltage source?

Answer 4

@ash2326 plz solve it

Answer 5

Ok, I'll try

Answer 6

The switch shown has been in position A for long time.
It means the cap is full charged from left side. Using my favorite
Thevenin's Theorem on the left hand side. I'll reduce the left part as
